Two of the main needs when developing an information system for an
organization are that system analysts know and understand the
application domain and that the system properly supports the business
processes of the organization. Consequently, elicitation of system
requirements from business process models has been acknowledged as a
suitable activity to deal with that needs. In addition, system requirements
must be linked to subsequent development stages.
However, system analysts can face many challenges when
performing these activities. They may have problems communicating
with customer stakeholders and may need to analyse and operationalize
the purpose of the information system. Furthermore, system analysts
must bridge the gap between business and system domains for
specification of system requirements, specify different types of system
requirements and guarantee that their specification is precise, consistent
and homogeneous.
In relation to object-oriented conceptual modelling-based
information system development, system analysts must also avoid
potential problems that may arise when a conceptual schema is created
from system requirements as part of their link with subsequent
development stages. For example, a conceptual schema can be
incomplete and/or inconsistent if it is not properly managed.
As a solution, this thesis presents a methodological approach for
business process-based requirements specification and object-oriented
conceptual modelling of information systems. The approach consists of
four stages: organizational modelling, purpose analysis, specification of
system requirements and derivation of object-oriented diagrams.
By following the design research methodology for performing
research in information systems, the methodological approach has been
designed on the basis of many existing ideas and principles in academia
and industry and provides new principles, mechanisms and guidance to
address the challenges presented above. / De La Vara González, JL. (2011). Business process-based requirements specification and object-oriented conceptual modelling of information systems [Tesis doctoral]. Universitat Politècnica de València. https://doi.org/10.4995/Thesis/10251/11445
